Here are some tips from the nonprofit National Institute for Automotive Service Excellence (ASE) on finding a good repair establishment:

• Start shopping for a repair facility before you need one.
• Ask friends and associates for recommendations; consult local consumer organizations.
• Arrange for alternate transportation in advance so you will not feel forced to choose a shop based solely on location.
• Look for a neat, well-organized facility, with vehicles in the parking lot equal in value to your own and modern equipment in the service bays.
• Look for a courteous staff, with a service writer willing to answer all of your questions.
• Look for policies regarding labor rates, diagnostic fees, guarantees, acceptable methods of payment, etc.
• Ask if the repair facility specializes or if it usually handles your type of repair work.
• Look for signs of professionalism in the customer service area such as civic, community, or customer service awards.
• Look for evidence of qualified technicians: trade school diplomas, certificates of advanced course work, and certification by ASE.
• Reward good service with repeat business and customer loyalty.
